@john_michael51 Building a free, explanation-first calculator suite that covers everything from mortgage amortization to BAC is a solid approach to a genuinely frustrating gap in the market. As you expand the category list, MentionFox's Reddit and forum monitoring can surface threads where people are actively asking "is there a free calculator for X" — giving you a direct pipeline of feature requests and potential early users without manual searching. That kind of demand signal is hard to replicate through guesswork alone. Check out https://mentionfox.com — in 30 seconds you can set up keyword alerts that turn public complaints about missing tools into your next build priority.
